Of particular note in this release are improvements to overprint and
spot color support in documents with transparency, improvements to PDF
and PS output, proper handling of PDF-specific text rendering modes and
support for reading AES-encrypted PDF documents.

Also improved is handling of CJK text, especially in vertical writing
modes, memory footprint processing some files at high resolution and
support for using the system's default paper size on unix.

The interpreter's handling of color spaces has been moved from
PostScript code to C.

A number of the included printer drivers and cups wrappers have been
updated to support a PDF-based workflow. Also fixed are several
long-standing bugs in the pcl drivers with respect to duplex, resolution
and paper tray selection.

Thanks to everyone whose hard work made this release possible!
